IMPROVEMENT IN WIND-WHEELS.

Specification forming part of Letters Patent No. 145,782, dated December 2f?, 1873; application filed September 27, 1873.

To all whom 'it may concern:

Be it known that we, PHILIPP BEA-ND, J osIAH BAERows, and ALEXANDER ARM- STRONG, of Jacksonville, in the county of Morgan and State of Illinois, have invented a new and Improved Vindmill, of which the following is a specication:

The invention is an improvement in the classiof wind-wheels mounted a little ont of line with the regulating-vane and adapted to be self-regulating. Ve arrange the wheel on a tubular support, which is iixed above the vane-support, so as to turiron a hollow shaft, and having a horizontal arm with a frictionroller on it, working in an ascending spiral slot formed in an arm of the vane-support, so that the wheel may swing around parallel with the vane out of the wind when the latter is too stron g, at the same time forcing the aforesaid arm up the inclined slot, so that the gravity of the wheel and its support will cause it to move back into the wind when the force of the wind decreases enough.

Figure l is partly a side elevation and partly a sectional elevation of our improved windwheel, and Fig. 2 is a plan view.

Similar letters of reference indicate corresponding parts. y

A represents ahollow shaft or tube, mounted in the hollow bracket B on the post C, so that it extends above and below said bra-cket. This bracket has a large annular, stud, D, ex-

n tending upward a short distance above the collar or flange E, to serve for the pivot of the casting F, to which the beam G of the tailvane H is attached, said casting being tted on the pivot so as to turn freely around it. OnV the side of the hole opposite to the beam, said casting has a clip, I, which works under the ilange to counteract the action of the weight of the vane on the pivot. J is a curved bar arranged on the casting E, with a slot, K, arranged spirally to the vertical axis of the machine, and at a distance from it suitable for the roller L of the arm M of the hub N of the wind-wheel to workin. This hub and arm are connected with a short vertical hub or tube, O, mounted on the shaft A above the pivot D, so as to rest on it except when raised by the slotted bars J. The hub O is free to turn, also to rise and fall, on the shaft A. The hub N is arranged to one side of the hub D so as not to be in the same plane ofthe tail-vane, the obj ect of which is, that the win d-wheel I shall tend to swing around to the right parallel with the tail, asin Fig. 2. The inclined slotted bar J and the roller-arm M oppose this tendency, and keep the wheel P at right angles to the vane andV out of the `wind, but will instantly turn it` Moreover,

back when the wind-force abates. the effect of the wind on the wheel will decrease as the latter turns out of it, so that the wheel will be graduated to the varying forces' of the wind within the limit of the force necessary to turn the wheel entirely around. To allow the wind-wheel to turn on the axis A without disturbing the connection with the pump-rod S, thc latter is arranged so as to turn on its axis, and is connected to a lever, T, that has afulcrum on the arm U, projecting from the hub D, which turns with the wheel I). The other end of said lever is connected, by rod NV, with the crank of the wind-wheel.

The tubular shaft A, through which the pumprod S works, is capable of rising and falling, and has a lever, X, combined with it, by which to lift thewheel up, and at the same time turn it out of the wind to stop it.

Having thus described our invention, we claim as new and desire to secure by Letters Patentl. In combination with the vane and its cast-ing or ring-socket E, provided with the spiral bar J having slot K, the wheel P, having an arm, M, working in. said slot, and supported on a hub, O, revolving independently oi' the vane, substantially as shown and described, whereby thc wheel may vary its posi- PHILIPI BRAND.
